Description

Implement the Cypress GitHub Action

Changelog

Added .github/workflows/web-cypress-tests.yml - defines the new GitHub Action
- Demonstrates
  - Using GitHub repo secrets within the .yml file for a GitHub action
  - Using working-directory to target a child directory to run the Cypress tests within
Modified web/cypress.json so that we now use up to 5 test retries (for some reason, many of the tests are flaky)
Modify existing tests to use base URL of localhost:9000 - this is the base URL for the gatsby serve site
- Should always test against the served version since this is basically the production site, run locally
